Proper No-Intro 1g1r collection of ROM sets:
- No bios files, bad dumps, hacks, fixed, patched, cracked, non-game or pirate ROMs.
- No unlicensed releases, protos, demos, betas, etc.
- All ROMs come from No-Intro ROM Sets (2024) and match the specifications from the DAT files — any ROM with a different CRC/MD5/SHA doesn't belong in the collection.
Retool was used for trimming all sets with its default region preference for English speakers and all languages included. The setup is detailed in this GitHub repository, which also documents the missing systems, and may also be used to file issues in case there's anything wrong with the collection:
https://github.com/proper1g1r/proper1g1r-collection
The collection includes a
DATs folder with 3 files for each system: a screenshot documenting the options used when generating the DAT file for that system on
DAT-o-MATIC, the DAT file generated, and the DAT file generated by Retool on top of it. This should be enough in case anyone wants to understand, replicate, or tweak the collection, or even use it as a way to check and verify their own collections.

What's No-Intro?
It's a group specialized in preserving cartridge-based games and digital content — it's thanks to their work we can be sure a ROM is a safe 1:1 dump of the original copy.
Myrient's FAQ has a brief explanation about it, and you can also check their website:

What's 1g1r?
1g1r stands for “one game one ROM” and it means having only one ROM per game, usually the one that matches your region and language preferences, and is the most updated and with the most features. A 1g1r set ensures there's no game repetition and that you're getting the best version of each game.
What are DAT files?
They're data files provided by No-Intro for ROM managers. They list ROMs of a given system, together with their checksums and hashes, and can be used with ROM managers (like
CLRMamePro,
RomVault,
Romcenter, or
JRomManager, which was the one used here) to trim ROM sets. You can see all DAT files used in the creation of this collection in the
DATs folder.
There's a game or system missing, a duplicate, an incorrect pick, or any other issue with this collection. How should I report it?

Will translations ever be included?
Why was Sonic The Hedgehog (Japan, Europe, Korea) (En) picked over Sonic The Hedgehog (USA, Europe)?
Why was Super Mario All-Stars + Super Mario World (USA) picked over the individual titles?
The compilation features updated versions of the games, and because of that
it's a superset. If you prefer the individual titles, you can fetch them from ChadMaster's set
here.
